写复杂XML问题。 ！！！！

Question

<?xml version="1.0" encoding="UTF-8"?><Licence_Service>
  <Version_1>
  <Version>1.0.0</Version>
  </Version_1>
  <SeriesNo_1>
  <SeriesNo>TH123456</SeriesNo>
  </SeriesNo_1>
  <Licence_Commands>
  <after_server_bootup index="1">
       <interval>N/A</interval>
  </after_server_bootup>
  </Licence_Commands>
</Licence_Service>要用程序把上面的内容写到XML文件里 

Answer 1

用VC 6.0实现。我有一个例子。但是我这个比较复杂。AfxEnableControlContainer();
    ::AfxOleInit();    ::CoInitialize(NULL);  xml::IXMLDOMDocumentPtr pDoc1;
 xml::IXMLDOMElementPtr xmlRoot;
 xml::IXMLDOMNodePtr xmlNode; 
 HRESULT hr1 = pDoc1.CreateInstance(_uuidof(xml::DOMDocument));
 if(!SUCCEEDED(hr1))
 {
   AfxMessageBox("无法创建DM对象！");
   return 0;
 }   xmlRoot = pDoc1->createElement("Book");
  xmlRoot->setAttribute("id","NO.1");
  xmlNode = pDoc1->createElement("Author");
  xmlNode->Puttext("Tom");
  xmlNode = pDoc1->createElement("Author");
  xmlNode->Puttext("Tom1");
  xmlRoot->appendChild(xmlNode);
  xmlRoot->appendChild(xmlNode);
  xmlNode = pDoc1->createElement("Title");
  xmlNode->Puttext("C++");
  xmlRoot->appendChild(xmlNode);
  pDoc1->appendChild(xmlRoot);
  pDoc1->save("c:\\1.xml");

Answer 2

从XML读出来，操做，再写回XML 读出来可以了。写文件。有点问题。

Answer 3

不会写这么复杂的XML不知道。怎么在节点下再建一个有子节点的节点。

Answer 4

appendChild一层层建下去，你这个不复杂的。

Answer 5

嫌麻烦的话，就去下载个CMarkUP用用

Answer 6

我试了，新的appendChild会覆盖
